ABSTRACT:
A trimmer line, hook disk system forming a line trimmer head (e.g., FIGS.10&10A,19&20) for attaching to a powered, rotational device (FIGS.11-16) to provide a line filament grasscutting/weed-removal action. The trimmer head preferably includes a circular, protective, bottom base (D2/60/160), a main trimmer head top (D3/D30/130), the two forming a disk shape, and a series of peripherally spaced, line holders; with these three basic elements fastened together for ultimate attachment to the powered31device. Ten exemplary line holder are shown (FIGS.1-9B), with most allowing oscillating (O) motion in their attachment to the trimmer device (D1), allowing the lines to move backwardly when contacting a relatively hard item, and/or some fixed (F). A “broom” embodiment is disclosed (FIG.17). When used, flexible line, e.g. of nylon, is inserted in (1) and held (2) by the line holders preferably using hook or hook-like line attachments.
